Something new

(Via TedBlog) The Internet has given us more than just easy access to pornography. We have new models of buying and selling (Ebay), seas of useful product information (Amazon) and the ability to listen to any music we want to hear (Itunes). Now you can use the net to multiply your giving or to create social change. There is a new site called Pledgebank where you pledge an action like "I will stop using X if y people pledge to do it too." Here is an example of a charitible pledge. Here is a political one. Other users can then sign on and pledge as well. I signed up to get updates if anyone in Portland makes a pledge. Seems like something that could be quite powerful.
